Not my fault you chose to eat the monkey bread first!
There's just so many of them that are good, so I feel you on the difficulty of that choice. I'd have to agree that the future of Twinborn and the rest of the Metallic Arts is intriguing.
It's probably the Feruchemical equivalent of the Tetris thing, where if you do something so much, you'll dream about it and sometimes act it out while asleep.
You can become a savant in just about any magic system, but Feruchemical savantism would probably result in greater control over tapping and storing, including being able to tap/store in localized areas of the body as opposed to everywhere.
Luckily for you, it wasn't spiked! What kind of tavern owner would spike their food? Not this one, that's who! You are suddenly incredibly refreshed by the monkey bread.
Would you like a cup of tea to wash it down?
